A novel search technique to solve load flow of distribution networks

Suman Bhullar, Smarajit Ghosh

Abstract


This paper suggests an unaccustomed way to make the load flow solution of the prevailing distribution networks (DNs) more efficiently. It is based on an in-depth study involving a novel search technique to find the link between all nodes in the feeder, lateral(s), and sublateralals(s)
with the aim of avoiding the repetitive search. The suggested method does not need any manual coding for source node of the feeder, lateral(s), and sublateral(s). The powerful search technique automatically forms arrays of nodes of the feeder, lateral(s), or sublateral(s). An expression of voltage equation is derived to compute the voltage of each node along with an expression of voltage angle to compute the angle of the voltage of each node. The suggested method has been tried out
on eight standard radial distribution networks (RDNs) including one practical Indian RDN to show its capacity of convergence. The proposed method is also examined on different types of load modelling of the existing practical system. The suggested technique has been also correlated with the other methods available in the field of RDNs. Distributed generation (DG) placement in 69- node RDN has also been done to show its capacity for handling DG. The suggested technique has
also been extended to mesh distribution network (MDN) and also for to unbalanced distribution network (UDN).
